Battlefield Contractor

Jonathan looked at Lin Rui's expression, he saw a solemn expression on this person's face for the first time.

But Jonathan is a smart man. Although he didn't know much about the specific situation of the secret society, he knew something from Lin Rui's current expression and the current situation.

So his expression became a little worried.

"Mr. K said before that the specific situation of the M3 laboratory has been leaked. Moreover, judging from the offensive launched by the other party, we chose the weakest southern side to launch the attack.

This all means that the attacker knows our situation quite well, but we know nothing about the attacker. It seems that the situation is really serious. "Jonathan whispered. "Mr. Rick, you tell me the truth, how long do you think we can hold on here?" "

"I'm afraid it won't be long." Lin Rui took a deep breath, "but we have to do our best to hold on."

"Tear gas!" a mercenary exclaimed. The attackers outside threw in several smoke bombs from the window. One of the experienced mercenaries knew it was bad when he smelled it.

This is not ordinary police tear gas, but military grade tear gas.

The spiciness of military tear gas is 5,300,000, which is more than twice the spiciness of police-grade gas used to disperse crowds.

"Wear a gas mask!" Lin Rui shouted loudly, "hold your position."

Fortunately, the place where they are located is a four-level laboratory, and all kinds of protective equipment are still complete.

All the personnel put on gas masks. For people who are not used to gas masks, wearing this kind of mask is actually a very bad experience.

The mask has a pungent rubber smell, and you can hear yourself through the mask, heavy breathing. If the temperature difference is large, the lens on the gas mask will also be covered with a layer of water vapor, which will interfere with the wearer's line of sight.

The solution is simple, but a bit disgusting. That is to use saliva to smear the inside of the lens of the gas mask to prevent fog interference.

After putting on the gas mask, there is almost no way to tell who is who, everyone is the same.

It's just that it's difficult to see a person clearly in a workshop full of smoke.

Several mercenaries picked up the tear gas on the ground and threw it out the window. This will cause the window to be full of smoke. The visibility of the enemy and the enemy has become very low.

But in this case, the mercenaries in the workshop still suffer. The militants outside can shoot at the location of the workshop, throwing grenades and tear gas to bombard wildly. The mercenaries in the workshop have nowhere to hide.

The situation became extremely critical. Fortunately, Lin Rui and the others had blocked the main entrance of the workshop.

Otherwise, the situation will become more difficult to control.

"All the teams hold their positions. We have to try our best to hold off the time." Lin Rui put on a gas mask, humming and ordering.

"Boss can't go on like this. The visibility is too bad. We can't see where the enemies outside are. But they can throw grenades and tear gas at us." Kuaima opened fire at the window and turned his head.

Before he finished speaking, a grenade was thrown in again.

Lin Rui rolled on the spot, picked up the grenade at his feet, and immediately threw it out with his backhand. The grenade exploded outside the window of the workshop, and a scream was heard.

This means that the enemy has rushed to a position quite close to the workshop.

Several other mercenaries immediately screamed in the direction and suppressed fire. Lin Rui knew that things had become serious.

They now have no other choice but to retreat into the underground laboratory. But this was the choice Lin Rui most didn't want to make.

Because he knew that once he did this, there would be no room for retreat. The secret society organization should have undergone careful arrangements for this attack. They will not fail to consider this situation, so there must be other ways to invade the underground laboratory.

But the current situation is if he does not make a choice. Neither these brothers nor Lin Rui could persist in this workshop for too long.

In the workshop full of tear gas, mercenaries were injured and fell to the ground from time to time. If this continues, everything will be too late.

Lin Rui made a decisive decision and ordered the mercenaries to shrink into the workshop. Another group opened the entrance of the laboratory. He had to lead the team to retreat into the underground laboratory and make the final resistance there.

Jonathan knew Lin Rui's thoughts. But he also knew that he had reached the point where he could not choose.

So he nodded to Lin Rui and cooperated with other soldiers to open the entrance of the underground laboratory.

"You are advanced, we will cover." Lin Rui shouted back.

The mercenaries withdrew into the underground laboratory in batches, and Lin Rui personally led a team of mercenaries to break. After a bitter battle, they finally withdrew into the underground passage.

"Come in quickly." Jonathan and Yelena, who had withdrawn first, waved at them at the same time.

When Lin Rui took the remaining mercenaries into the underground passage. The heavy closed gate began to close, and finally closed tightly.

Lin Rui leaned against the door and tore off the gas mask on his head. His face was sweaty and he was breathing heavily.

"Damn. These guys are all premeditated." Sergey put the gas mask in his hand to the ground angrily.

"It's only eight minutes." Lin Rui looked at his watch with a serious expression. "I originally planned to stay in the upper workshop for 20 to 30 minutes. This might effectively delay the enemy. But now..."

"They have plenty of time." Kuaima nodded, "The other party is well prepared. They have made specific arrangements for this attack. This is something we can't do."

"It has been a few minutes since the communication was interrupted?" Lin Rui asked, turning his head.

"Less than twenty minutes." Kuaima said with a stern look, "The drones with the swarm communication jamming system will last about one hour and twenty minutes. We have to hold on for at least an hour before we can continue to communicate.

"It's more serious than this." Lin Rui sighed. "Underground facilities are in a shielded state and cannot directly send wireless signals, but can only be forwarded through ground communication systems.

And now they have taken control of it, just unplug a few cables or turn off the upper communication system to keep us silent forever.

In other words, we may never be able to contact the outside. "

Everyone's faces are quite heavy. Now there are all enemies outside, and they can only be trapped in this underground laboratory.

Lin Rui stood up and took a deep breath. To Jonathan, "You go and inform the laboratory personnel and tell them that a terrorist attack has occurred. Collect all the personnel. Move to a relatively safe place. We may face the worst situation."
